LINOTYPE-MAfCHINE.

SPECIFICATION forming part of Letters PatentNo. 657,429, dated September 4, 1900.

Application filed March 31,1900. 'jserii No. deas. on model.)

To all whom it may concern.-

Be it known that 1, JOHN H. LYNCH, of New York, county of New York, and State of New York, have invented a new and useful Improvement in Linotype-Maohinesof which the following is a specification. a

My invention relates to improvements in the mechanism for delivering type or type matrices one ata time from a magazine or holder and assembling them in line in the required order.

Many machines are known" in the art in;

termined time haselapsed after the action of which type and type-matrices (which as regards the purposes of this invention are to be considered as equivalents) are released one at a time from the respective channels 'or grooves of a magazine, the releasing de vices'being actuated orset in motion by finger-keys or equivalentcontrolling devices.

One of the chief difficulties encountered ini the operation of these machines at high speed lies in the transposition of the characters, due to the fact that the type are released from the magazine atvarying' distances from the point of assemblage, so that the time required for the passage of certain type from the point of release to the composed line is much greater than that required for the passage of other type. Many mechanisms have been devised to overcome this difficulty, the plan generally employed being that of using a carrier belt lying at an angle to the mouth of the magazine, so that type which have the greatest distance to travel are received on the belt immediately upon being released,while the type which would otherwise have a less dis:

tance to travel are required to move a cone 1 siderable distance after leaving the magazine before they reach the carrier-belt. Now this oblique arrangement of the carrier-belt is attended necessarily by other peculiarities of constructionin the machine which are .-open Now the object of my invention is to overQ come these difliculties and provide an assemblingmechanism in, which the type maybe carried in very rapid succession to the line without danger of transposition andwithout the employment of the obliquely-arranged carrier. To this endit consists in a poweris controlled, while on the other hand an escapement located nearer the point of assembetween the actuation of a key andthe movement of the corresponding escapement increases from key to key as the point of assemblage is approached.

Fig. 3 is a top plan view of one end of the driven mechanism in which the escapement or releasing devices start at a longer or a shorter interval after the actuation of the {finger-key, according to the distance ofthe escapement from the point of assemblage.

"In other words, in my mechanism an escapement or discharging device remote from the ,pointof assemblage starts instantly upon the touching of the finger-key by which it blag'e' does not begin its'actionuntil a predeits controlling-key. The time which elapses In consequence of this arrangement a key near the assemblingpoint may be operated quickly after a key at a remote point; but the action of the second escapement will be delayed sufficiently to per rnit "the type released by the first key to reach the line in advance of the type released by the second key, although the letter may be much nearer the assembling-point; or, to state the matter differently, the fingering of the keyboard is followed by the release of 1 each type a little more quickly than the re- J lease of the type next nearer the point of assemblage. Consequently it is possible for the operator to manipulate the keyboard at ihigh speed and Without considering in any manner; the distance which the respective type have to travel land without danger of transposing them in the line.

i For: the purposes of illustration I have shown my invention as incorporated in a linotype keyboard mechanism of the general char acter represented in Letters Patent to P. T. 0 Dodge, No. 530,931, dated December 18, 1894.

into the assembling-elevator, inwh ien' 1th am 0 the parts in 'theiDndge patent 'IQfiQI'IQd to, except as to the feature In the Dodge patent the various cams in the row Qh avetheiiristop-shoulders in one and the same position and the stop-pins are arranged in a line parallel with the axes of the cams, so

that the actionvv of allnth e'esoapements is practically. in stantan eons when the correspondin g keys are depressed. "I arrange the stop-shoulders of the sn g 1 at dif er nt dis I 11 ,1 hi li 'npiefs "the 919-1. 3' it. at apoint' farther to the ef from; pointn gte i tha l P ,The g nera h I)" se ect of t trix released from any part of the magazine will reach the line in advance of a matrix previously released.

Instead of the foregoing arrangement for operating the escapements in different times I may employ an arrangement such as shown in Fig. 5, involving the same principle. In this instance the cams are all made alike and arranged to stop in like relations to the underlying roll; but the roll is tapered or conical in form, with its larger end remote from the point of assemblage, so that the cams engaging the roll at difierent points in its length will be revolved at difierent rates of speed,

the speed increasing with the successive cams from the left toward the right. When,therefore, a key at the right of the keyboard is actuated, its cam will be turned very rapidly and its escapement operated immediately, while a cam at the left of the keyboard on being released will turn at a comparativelylow rate of speed, so that its escapement will not be actuated to release a matrix until the matrix released .by the first escapement has passed on its way to the line.

The essence of the invention lies in the time-controlled keyboard so arranged that the matrices represented by difierent keys will be discharged at a longer or a shorter interval after the actuation of the key, according to the distance which the matrix is required to travel in passing to the line from the magazine.

It will he manifest to the skilled mechanic that themechanism may be widely modified in detail without passing beyond the limits of my invention..

What I claim as my invention is 1. In a composing mechanism, the combination of type-discharging devices, corresponding finger-keys,and intermediate mechanism to vary the interval between the action of the respective keys and discharging de vices, according to the time required for the type to pass from the respective discharging devices to the point of composition.

2. In a composing mechanism, a series of time controlled type discharging, devices, graduated as to their relative speeds according to the time required for the travel of the respective type, substantially as described and shown.

3. In a composing mechanism, the combithe interval of time between the operation of a key and the operation of the corresponding discharging device and giving a greater interval for those devices which are near the point of assemblage than for those which are remote therefrom.

In testimony whereof I hereunto set my hand, this 30th day of March, 1900, in the presence of two attesting witnesses.

JOHN H. LYNCH.
